The overall arrangement and technical solutions of hydraulic skidmounted live well workover rig were introduced, on the basis of its different technical requirements. And in the technical solutions, the hydraulic principle diagrams of the hydraulic control pumping station, control valve group one, two, three were given.For each hydraulic principle diagram, the control processes of each components was shown,meanwhile how to solve the problems like the hydraulic cylinder interlock and the antiexplosion mode of electrohydraulic proportional pump was discussed.It has good removability, reasonable structure and be able to complete the mission.
